Description

2,5,8,11-Tetraoxatridecane-13-Thiol CAS NO 52190-55-3 is a specialized thiol-terminated polyether compound, valued for its unique combination of a flexible polyether backbone and a reactive thiol (-SH) functional group. This structure makes it a versatile building block and surface modifier, particularly useful in applications requiring controlled reactivity and compatibility with various polymer matrices. It is primarily sought by R&D and production teams in the polymer, adhesive, and specialty materials industries for creating advanced functional materials.

Application

• Polymer Modification & Crosslinking Agent: Used as a chain transfer agent or crosslinker in the synthesis and curing of polyurethanes, epoxies, and other polymers to introduce flexibility and specific end-group functionality.
• Surface Functionalization & Adhesion Promoter: Employed to modify surfaces (e.g., metals, oxides, polymers) by forming self-assembled monolayers (SAMs) or as a primer to enhance adhesion in coatings and composite materials.
• Pharmaceutical & Bioconjugation Intermediate: Serves as a valuable linker or spacer in the synthesis of drug conjugates, diagnostic agents, and PEGylated compounds due to its polyether chain and thiol reactivity.
• Lubricant & Fuel Additive Component: Acts as an intermediate in formulating multifunctional additives where the thiol group provides anti-wear properties and the polyether chain offers solubility.
• Specialty Chemical Synthesis: Utilized as a key intermediate in organic synthesis for creating complex molecules with tailored solubility and reactivity profiles.

Quality Control

Our 2,5,8,11-Tetraoxatridecane-13-Thiol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay (by titration or GC), identity confirmation (IR, NMR), and impurity profiling to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, minimize exposure to air and moisture during handling and storage.
